Mid infrared

Mid-wave infrared: 3 to 5 μm (defined by the atmospheric window and covered by indium antimonide [InSb] and mercury cadmium telluride [HgCdTe] and partially by lead selenide [PbSe]). Long-wave infrared: 8 to 12, or 7 to 14 μm (this is the atmospheric window covered by HgCdTe and microbolometers) Mid-infrared spectroscopy is a very important and widely used sample characterisation and analytical technique, whether the sample is in the form of a gas, a liquid, paste-like, or solid

2.1 Mid-Infrared Spectroscopy MIR spectroscopy relies on light absorption. Incident IR light upon a sample causes biochemical bonds to vibrate. Vibrational modes of molecule thereby cause specific amounts of energy from the incident IR beam to be absorbed, reducing the intensity of the subsequently detected IR beam Mid-Infrared: the molecular fingerprint region. Mid-infrared (mid-IR) radiation - typically defined as 2.5-10 µm wavelengths (although the exact values can vary) - is not something many of us come across in our daily lives. We can't see it and we don't use it for data transmission either The mid-infrared spectral region is the most interesting region for the development of SC sources since it contains the fundamental absorption of several materials and molecules. Mid-IR SC lasers thus find applications mostly in imaging and spectroscopy. Here are some of their most promising applications
